About Polycode
Polycode is a native macOS application that dispatches each user prompt to multiple AI providers simultaneously—such as Claude, GPT, Gemini, Apple Intelligence, and others—and then synthesizes their responses into a single, traceable answer. It supports both cloud-based models and on-device Apple Intelligence Foundation Models, routing traffic through the Neural Engine when local execution is selected. Users supply their own API keys, and the tool aggregates costs per exchange rather than per session, allowing for transparent billing. Each provider’s reply is displayed in parallel with latency, token usage, and cost details, and a primary peer model writes the final consensus answer. The application includes a built-in inspector that shows full provider traces, minority responses, and tool-call histories, enabling users to audit decisions and share detailed logs. It is designed for developers, researchers, and teams who need to compare model outputs, debug consensus failures, or reduce tab-juggling across multiple AI interfaces.

Frequently asked questions about Polycode
What is Polycode and how does it work?
Polycode is a native macOS application that sends each user prompt to multiple AI providers simultaneously, such as Claude, GPT, Gemini, and Apple Intelligence. It then synthesizes their responses into a single, traceable answer while displaying each provider’s reply in parallel with latency, token usage, and cost details.
Who is Polycode designed for?
Polycode is designed for developers, researchers, and teams who need to compare model outputs, debug consensus failures, or reduce tab-juggling across multiple AI interfaces.
Does Polycode support on-device AI models?
Yes, Polycode supports on-device Apple Intelligence Foundation Models, routing traffic through the Neural Engine for local execution when selected.
How does Polycode handle billing and costs?
Polycode aggregates costs per exchange rather than per session, allowing for transparent billing. Users supply their own API keys, and the tool provides detailed cost breakdowns per provider.
Can I use Polycode with my existing API keys?
Yes, Polycode allows users to bring their own API keys, including support for OpenRouter and other compatible providers.
How do I get started with Polycode?
Polycode is available as a native macOS application on the Mac App Store. Users can download it and start using it immediately with their configured providers.
